vsto - Translate a Excel Range to a row/col -

I have looked completely but have not found any answer on this ...

Quite Simple I have a VSTO Excel 2007 project that I want to be able to translate the row 1, column 1 integers to a cell (for example "A1")

Is anyone aware of a built-in method for this, or do I have to write my parser?

You can;

  R = range ("AP100")  

then r.row and r.column Their numerical index will return.
